CARRIAGE-JACK.

SPECIFICATION forming part of Letters Patent No. 333,807, dated January 5, 1886.

Application filed November 23,1885. Serial No.183.692. (No model.)

To all whom it may concern:

Be it known that I, PASCHAL J OB ABBOTT, of Dexter, in the county of Penobscot, of the State of Maine, have invented a new and useful Improvement in Carriage-Jacks; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a front elevation, and Fig. 2 an edge View, of a jack of my invention, the nature of which is defined in the claims hereinafter presented. The above figures show the parts of the jack in the positions they assume on a carriage-axle having been raised by it. Fig. 3 is a side view of the jack, exhibiting its lever as depressed preparatory to applying the jack to the axle of a carriage for the purpose of tipping upward such axle and one of the wheels thereof.

In such drawings, A denotes a lever, provided at itslower end with a wide foot, a, and near its upper end with a bolt, B, adapted to slide on one side of such lever,lengthwise thereof. and to engage with a notch, b, in the upper end of a broad and flat arm, 0. The said arm, formed as shown, is pivoted near its lower end to the lever A, the arm having on its upper end a series of notches, 0, arranged like the steps of a stair, all being as shown. The arm is placed flatwise on one side of the lever, and is connected thereto by a headed bolt or pin, d, which goes through the arm and the lever, the arm turning freely on the bolt.

To use the jack the lever is to be moved down to an angle with the arm, as represented in Fig. 3, and, with the arm, is to be extended under a carriage in a manner to have its axle enter one of the notches c. This having been done, the lever is to be turned upward into a vertical position, after which the bolt B is to be forced down into the notch 1). While the lever is in the act of being so turned upward the heel of its foot will bear on the ground, and the carriage will be raised so as to lift off the ground the wheel to be operated on. In rear of the notch b the top of the arm 0 is inclined, as shown at f. The lever A, being raised sufficiently, will carry the bolt against the incline f. The further advance of the lever causes the bolt to be moved up the incline, or forced upward thereby, and generally in coming directly over the notch b the bolt will, by its gravitating power, drop therein. If desirable, the bolt may be provided with a spring to insure its passage into the notch.

I claim-- 1. The carriage-jack, substantially as described, consisting of the lever A, the bolt B, and the notched arm 0, constructed, arranged, and combined essentially as set forth.

2. The combination of the lever A and the sliding bolt B, applied thereto, with the arm (J, pivoted to such lever and provided with the series of notches c, the recess b, and incline f, arranged in it, (the said arm,) as set forth.
